           Summary: Connection reset by peer: socket write error  /  Error
                    500 when uploading a file in Bb 6.2.2
           Product: Tomcat 4
           Version: Unknown
          Platform: PC
        OS/Version: Windows Server 2003
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: zee.nagre@westking.ac.uk


We have a Windows 2003 cluster config , SQL Server 2K and  using Tomcat 4. 
Every now again (about 50 times a day)  when an instructor tries to upload a 
file  in Blackboard 6.2.2 we get a  Error 500 in IE Explorer 6. Closing down 
the browser and trying again usually works but sometimes the error persists. We 
have opened a ticket with Bb but  have found out the it's usually quicker to 
get a solution here. I have replicated part of  Tomcat's log below.
TIA.
